DNS Monitoring Improves Web Site Speed and Reliability – Part 1

The only way to know how well or how reliably DNS servers perform is to make consistent, regular objective tests and measurements over time. While DNS servers can be verified manually, that is not a practical solution. Manually checking the DNS servers a few times a week, or even a few times a day, simply does not provide enough data to accurately judge performance, nor does it quickly alert website owners to problems. Automatic DNS monitoring gives website owners the information needed.

Monitoring the Cloud – Cloud Monitoring for Application Management

Cloud-based applications with poor performance cost companies lost revenues and customers. In fact, as cloud apps become more complex more performance issues can occur, resulting in lost conversions and higher rates of website abandonment. Therefore, companies running cloud web applications need to continually monitor for performance issues, functionality and availability.

Traditional web applications sit on static servers inside a data center behind company firewalls. This delivery chain is fixed with minimal variables. Cloud applications, however, are more complex by nature. Here the application delivery chain moves from an end-user through a browser (PC or mobile device), across the Internet (through a local ISP, or mobile carrier), through a third-party (cloud provider, or content delivery network (CDN)), into the complex infrastructure of a data center. All of these elements are essential to a cloud-based application’s performance making cloud testing and cloud monitoring much more challenging than traditional application performance management.
